BACS is an advanced, 3rd generation battery management system.
The system comprises of 4 main parts
A module is connected to each battery. It monitors for temperature and impedance, while actively adjusting the battery voltage to ensure the voltage is set at the UPS charger level. This process is called equalisation.
When actively monitoring and equalising batteries yields the following benefits
The BACS® WEB-MANAGER acts as the battery system‘s central control unit. It gathers, evaluates, and stores system information. The user is provided access to three web server pages. One displays the actual status of batteries; a second shows actual UPS data; the third shows environmental data and alarm contacts status. The web browser interface of the system is designed for easy configuration. It provides the user with access to all system values and events. A flexible programming interface known as the EVENT MANAGER coordinates a system response to significant events (alarms, notifications, etc.).
The WEB-MANAGER handles events involving the UPS, inverters, environmental sensors, transfer switches, generators, dry contacts, and other devices.UPS/SNMP & MODBUS MANAGER
BACS® includes a full qualified UPS/SNMP and MODBUS manager, one that is compatible with any UPS presently on the market! Among BMS systems on the market, this function is unique.MODBUS/PROFIBUS/LONBUS/SNMP
BACS® allows MODBUS clients to read the system data through IP and RS232 (and, optionally, RS485), as well as through SNMP. Conversion to PROFBIS and LONBUS is possible through optional converters.FREE VIEWER ANALYSIS SOFTWARE
Provides graphical BACS® data analysis and reporting.
BACS® has the ability to send out ―advance warning alarms via email, email-to-SMS, network message, SNMP, RCCMD, MODBUS, and, optionally, PROFIBUS, LONBUS, and GSM. (Alarm parameters can be configured by the user to match battery type.)
For instance, discovering rising internal resistance in a battery—an indicator of corrosion or sulfation— BACS® triggers an alarm.
Given early warning of issues, the user is able to investigate and take action far in advance of the consequences that can result from them. The effects of corrective actions taken are immediately observable. In addition to internal resistance, BACS® monitors voltage, temperature, the equalising process, the system‘s charging/discharging cycles, and, optionally, current. When pre-set thresholds of these categories are crossed, an alarm is communicated.
In addition to sending network alarms, BACS® also warns users via audible and visual signals (a buzzer on the BACS® MANAGER and alarm LEDs on the module and BACS® MANAGER).
BACS has the ability to integrate UPS monitoring and alerting via the serial port. Over 1400 UPS manufacturers are supported.
